Ascension: Realms Unraveled

Ascension: Realms Unraveled is a deck-building game in which players acquire cards from a central pool, then place those cards in their discard pile to be shuffled into their deck for later use; creatures also show up in that shared card pool, and players can combat them to earn victory points (VPs) and possibly other benefits, such as the ability to remove less useful cards from their deck or to banish cards from the pool that others might find useful. The game ends once all the available VPs have been claimed or the shared deck of cards runs out.
Ascension: Realms Unraveled, part of the Ascension deck-building game series, is both a standalone game for 2-4 players (with solitaire rules included, too) and an expansion that can be combined with any other Ascension game to support up to six players.
While cards in previous Ascension games have always belonged to one of four factions, Ascension: Realms Unraveled introduces multi-faction heroes, and these heroes combine with the new "Multi-Unite" game mechanism to deliver huge rewards to those who play multiple heroes from the same faction.
